[Resolved]  Sony Ericsson W810i — no response from service centre

I am using sony ericson w810i from last one year.From last one month I was getting problem as the keypad and menu keys.,joystic were not working so I had given it to service centre at bangalore at below address aft confirming it from sony cutomer care no.

As I had given the mobile on 14th Jan,08 I was told to collect it aft three days.When i went on 18 th jan to collect it they told me that it's have some motherboard problem so i need to wait for ten days i.e they will replace the mother board and give me back on 24 th.
As today I went to collect it they have another story.Nobody from customer care is sure when it will be repairied and given back to me.
Also whenever i am calling them either nobody is picking up the dam phone after twenty thirty rings and if by chance sombody will pick up they don't know anything.Even one mr. maninan had given me his mobile no but he is never answering his phone.

i don't know what to do as I asked them to give me back my phone without repairs.
